The performance of cities is crucial to the performance of
the UK economy. They account for 9 per cent of land use, but 54 per cent of population, 59 per cent of jobs and 61 per cent of output. But as well as being important in terms of scale, they are also important in terms of efficiency.
Cities in the UK produce 15 per cent more output for every worker than non-city areas, while they produce 32 per cent fewer carbon dioxide emissions than non-city areas.
